Objective      To investigate the anxiety and depression characteristics of patients before myoporthosis operation.       Methods      A total of 718 patients (16-42 years old) were tested before myoporthosis operation using self-rating depression scale (SDS) and state-trait anxiety inventory (STAI) to analyze their emotional characteristics.       Results      The depression positive rate was 39.69%

state anxiety positive rate was 48.89%

and trait anxiety positive rate was 59.47% among the patients before myoporthosis operation. The depression positive rate of male patients was significantly lower than that of female patients (P0.01). SDS scores of the patients before myoporthosis operation were significantly higher than those of Chinese norms (P0.01). There was no significant difference in STAI scores between the patients and the norms (P0.05).  SDS scores of male patients before myoporthosis operation were significantly lower than those of female patients (P0.01)

but the STAI scores had no significant gender difference (P0.05). The state anxiety scores of the patients before myoporthosis operation had significant difference (P0.05)

and the state anxiety scores of moderate and severe myopia were significantly higher than those of mild myopia (P0.05).       Conclusion      The anxiety and depression incidences of the patients before myoporthosis operation are high. Depression and state/trait anxiety show significant gender and myopia degree development characteristics.
